Thanks for watching!
This video explains antenna wire selection, focusing on material properties like conductivity and skin effect, which influence resistance and signal loss. Understanding these elements is crucial for any ham radio antenna or amateur radio antenna setup. It also touches upon radiation resistance and how velocity factor determines the electrical length of the wire, a key concept in electrical engineering and transmission line theory.
In this video, I take a $500 “dumb” repeater and replace the proprietary controller with software, a $30 Raspberry Pi, and a home-built interface cable. No locked menus. No vendor software. No magic boxes.
This is not a GMRS tutorial and it’s not about rules, brands, or menus. It’s about a pattern:
when the controller becomes optional, everything changes.
If you’ve ever looked at a piece of hardware and thought “this should be software”, this video is for you.

Where possible, all links are affiliate links, this youtube thing is an expensive endeavor and every little bit helps.
A custom controller board and some ham-genuity transforms this repeater. See how a Pi 4 (or even a $30 Pi Zero 2 W) can give new life to old tech. Cable pinout link below! #hamradio
DIY Arduino Project: Connecting Boards with Pin Headers #shorts
Easily connect two boards using pin headers! Place male pin headers on the bottom board, then add pin sockets. This method ensures proper alignment and secure connections.
🚀 Turn your old radios into digital-mode powerhouses! In this video, I show you the TOADs DI board and the new DI6 daughter board — a plug-and-play sound card interface that connects your radio to your computer over USB-C.
With just one board, you can run:
• Winlink 📡
• APRS 🚗
• FT8 🌐
• ANY digital mode you want
No more struggling with cables, custom wiring, or expensive interfaces — the TOADs DI6 makes it simple. (Of course if you like that kinda thing, the TOADs DI is for you!)
📌 In this video, I’ll show you:
• What the DI6 is and how it works
• How to connect it to your radio & PC
• Live demo of digital modes in action
• Why it might be the easiest way to bring your rig into the modern digital world

Jason inquires about short end-fed antennas, leading to a discussion on the "Shorty 40," a 40-meter end-fed half-wave antenna ideal for small yards. This amateur radio antenna includes a coil after the 20-meter resonant point, making it a good solution for both attic and outdoor mounting. This ham antenna, an efhw antenna, has an overall length of 42 feet and efficiently functions as a HF antenna without needing a tuner.
